TERMINAL D'AFFICHAGE D'ELEMENTS D'UNE BASE DE DONNEES HIERARCHISEES A N NIVEAUX

The invention relates to a display terminal for elements of a hierarchical database with n levels, at least some of the elements of the database belonging to a same hierarchical level having an association relationship, the terminal including at least two display parts (30, 32, 34). A first part (30) is intended to display a depiction by hierarchical levels of the elements of the database and a second part (32) is intended to display a graphic interaction object (36), having n display activation/deactivation zones (38a-38h), each display activation/deactivation zone (38a-38h) corresponding to a hierarchical level in the first display part (30). The terminal further includes a level filtering module and a display rearrangement module, said display activation/deactivation zones (38a-38h) being accessible to an operator of the terminal to command the level filtering and display rearrangement modules, so as to obtain a selected display depiction of the database. The terminal further includes means for selecting a central display level, the display of the selected central display level not being able to be deactivated via said activation/deactivation zones (38a-38h).
